We would like to develop a list of common variables for a database on otter road casualties so that each country can have the chance to collect standardised data. Here we report a list of variables as an example so that we can have a starting point for discussion. Please let us know what you think about this list and if you think we should remove or add any variable. At the moment this is just a list, but, if it is useful, we can work toward building up an actual database mask with a number of linked tables. Our idea is that each country should collect and retain its own data, but we would like to offer a platform where to discuss and present the kind of variables that may be useful to collect.

The idea of developing a database for minimum standards was born during a discussion of otter experts at the X International Otter Colloquium in 2006 in Korea.
